I have recently added Vitargo carb supplement to my pre/intra/post workout drinks. I am noticing a nice boost in energy, pumps and recovery, my strength is getting better as well. It has only been a week and a half, but I am really noticing the difference. I train at 5am so I can't eat before I go, the carbs get into my system quick and give me the fuel to hit it hard and not fade at the end.
